The  Gurudwara Bangla Sahib Delhi was once a bungalow that belonged to the Raja Jai Singh of the Amer in the 17th century and was called Jaisinghpura Palace at that time. When Guru Har Krishan the eighth Sikh Guru visited Delhi in the year 1664, he stayed over at the palace itself. During the stay of the Guru, there was an outbreak of cholera and smallpox in the region, which led to several people losing their lives. People of the region have never witnessed such an outbreak.

Guru Har Krishan dedicated his services to the suffering following the teachings of Sikhism by giving fresh water from the well, many were cured after drinking the holy water. Unfortunately, the  Guru contracted the same, which turned out to be fatal and he died on March 30, 1664. 

Later on, Raja Jai Singh of the Amer had constructed a small tank over the waters of the well, and it is now popularly believed to have the powers to heal all kinds of diseases and health problems. Devotees coming to Bangla Sahib from all over the world take the water in bottles as souvenirs.

The edifice of Gurudwara Bangla sahib Delhi is a magnificent example of Sikh architecture. The entire structure is carved out of a delicate white marble, with the central dome being covered in solid gold leaves. The front wall is decorated with intricated projected carvings and has various smaller domes.
